Creare una finestra di dialogo con diversi widget
Introduzione
Questo è un esempio di creazione di dialoghi con PySide.
In questo esempio, l'intera interfaccia è definita in Python. Sebbene ciò sia possibile per interfacce di piccole dimensioni, per le interfacce più grandi si raccomanda di creare i file .ui tramite Qt Designer e caricarli nel programma.
Method 1
An example of a dialog box complete with its connections.

Here the code to display the icon on the pushButton, change the name for another button, (radioButton, checkBox) and the path to the icon.
# Affiche un icône sur le bouton PushButton
# self.image_01 = "C:\Program Files\FreeCAD0.13\icone01.png" # the name of the icon
self.image_01 = path+"icone01.png" # the name of the icon
icon01 = QtGui.QIcon()
icon01.addPixmap(QtGui.QPixmap(self.image_01),QtGui.QIcon.Normal, QtGui.QIcon.Off)
self.pushButton.setIcon(icon01)
self.pushButton.setLayoutDirection(QtCore.Qt.RightToLeft) # This command reverses the direction of the button
The command UserAppData gives the user path AppHomePath gives the installation path of FreeCAD
# path = FreeCAD.ConfigGet("UserAppData")
path = FreeCAD.ConfigGet("AppHomePath")
This command reverses the horizontal button, right to left.
self.pushButton.setLayoutDirection(QtCore.Qt.RightToLeft) # This command reverses the direction of the button
Method 2
Another method to display a window, here by creating a file QtForm.py which contains the header program (module called with import QtForm), and a second module that contains the code window all these accessories, and your code (the calling module).
This method requires two separate files, but allows to shorten your program using the file ' ' QtForm.py ' ' import. Then distribute the two files together, they are inseparable.
The file QtForm.py

def show(self):
self.createUI()
self.retranslateUI()
self.window.show()
def setText(self, control, text):
control.setText(_translate(self.title, text, None))
The calling file that contains the window and your code.
The file my_file.py
The connections are to do, a good exercise.
